Description

Technical Field

[0001] This utility model relates to the field of vibration equipment technology, and in particular to a vibration device for making concrete test blocks. Background Technology

[0002] Concrete test blocks are crucial specimens used in construction engineering to test the strength, durability, and other properties of concrete. Their fabrication quality directly affects the accuracy of the test results. Vibration is one of the core procedures in concrete test block fabrication. Its purpose is to remove air bubbles from the concrete, ensuring it is dense and uniform, and preventing insufficient vibration that could lead to porosity within the test block, thus affecting the reliability of the test data.

[0003] Currently, existing concrete test block vibration devices have the following drawbacks: First, the vibration method is singular, mostly fixed-position vibration or unidirectional moving vibration, making it difficult to achieve all-round vibration of the concrete interior, which easily leads to local insufficient compaction; Second, the connection between the vibrator and the drive mechanism is fixed, making disassembly and assembly inconvenient, which not only affects the efficiency of test block removal but also increases the difficulty of cleaning the vibrator. Therefore, we propose a vibration device for concrete test block preparation to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a vibratory compaction device for making concrete test blocks.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A vibratory compaction device for making concrete test blocks includes a base, a U-shaped frame fixedly mounted on the top of the base, a rotating disk rotatably mounted on the top of the base, a positioning sleeve fixedly fitted on the top of the rotating disk, and a cylinder for placing concrete placed inside the positioning sleeve; a lead screw seat slidably mounted on the inner wall of the top of the U-shaped frame, a vibratory motor fixedly mounted on the bottom of the lead screw seat, an installation sleeve mounted on the output shaft of the vibratory motor via a detachable structure, a vibratory rod fixedly mounted on the bottom of the installation sleeve, a servo motor mounted on one side of the U-shaped frame, a reciprocating lead screw mounted on the output shaft of the servo motor, and the lead screw seat fitted onto the reciprocating lead screw.

[0007] Preferably, a stabilizing seat is installed on the top inner wall of the U-shaped frame. The stabilizing seat has a rotating hole, and one end of the reciprocating screw passes through the rotating hole and is rotatably connected to the stabilizing seat.

[0008] Preferably, a guide groove is provided on the top inner wall of the U-shaped frame, a guide seat is installed on the top of the lead screw seat, and the guide seat is slidably connected to the guide groove.

[0009] Preferably, bolt grooves are provided on both sides of the output shaft of the vibrating motor, and bolt holes are provided on both sides of the inner wall of the mounting sleeve. The bolt holes are threaded with anti-loosening hexagonal bolts that are compatible with the bolt grooves.

[0010] Preferably, a drive shaft is rotatably mounted on the top of the base, and the top of the drive shaft is rotatably mounted on the inner wall of the top of the U-shaped frame. A driven bevel gear is fixedly mounted on the drive shaft, and a drive bevel gear that meshes with the driven bevel gear is fixedly mounted on one end of the reciprocating screw.

[0011] Preferably, a rotating gear is fixedly mounted on the transmission shaft, and a rack that meshes with the rotating gear is mounted on the outer side of the rotating disk.

[0012] Preferably, the bottom of the base has a rotating hole, a rotating shaft fixedly connected to the rotating disk is rotatably installed in the rotating hole, and multiple shock-absorbing pads for shock absorption are installed at the bottom of the base.

[0013] Preferably, a controller is installed on one side of the U-shaped frame, and both the servo motor and the vibrating motor are electrically connected to the controller.

[0014] The beneficial effects of this utility model are:

[0015] 1. The reciprocating screw is driven by a servo motor to rotate, which drives the vibrator to move back and forth. At the same time, through the transmission cooperation of the drive bevel gear, driven bevel gear, transmission shaft, rotating gear and rack, the cylinder is driven to rotate slowly. This enables the vibrator to achieve a compound motion of reciprocating movement and cylinder rotation inside the concrete, realizing all-round vibration without dead angles, effectively removing air bubbles inside the concrete, ensuring uniform density of the test block, and improving the quality of test block production.

[0016] 2. The vibrator is detachably connected to the output shaft of the vibrator motor via an installation sleeve and an internal hex bolt. After vibration, the installation sleeve and the vibrator can be quickly removed, which facilitates the removal of the cylinder to demold the test block and allows for thorough cleaning of the vibrator to avoid concrete residue affecting subsequent use.

Detailed Implementation

[0023] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0024] This application discloses a vibratory compaction device for making concrete test blocks.

[0025] Reference Figure 1-5 A vibratory compaction device for making concrete test blocks includes a base 101, a U-shaped frame 102 fixedly mounted on the top of the base 101, a rotating disk 103 rotatably mounted on the top of the base 101, a positioning sleeve 106 fixedly fitted on the top of the rotating disk 103, and a cylinder 104 for holding concrete placed inside the positioning sleeve 106; a lead screw seat 201 slidably mounted on the inner wall of the top of the U-shaped frame 102, a vibratory motor 202 fixedly mounted on the bottom of the lead screw seat 201, an installation sleeve 203 mounted on the output shaft of the vibratory motor 202 via a detachable structure, and a vibratory rod 204 fixedly mounted on the bottom of the installation sleeve 203; a servo motor 402 mounted on one side of the U-shaped frame 102, a reciprocating lead screw 403 mounted on the output shaft of the servo motor 402, and the lead screw seat 201 fitted onto the reciprocating lead screw 403 and threadedly engaged with the reciprocating lead screw 403.

[0026] In this embodiment, a stabilizing seat 401 is fixedly installed on the top inner wall of the U-shaped frame 102. The stabilizing seat 401 has a rotating hole. One end of the reciprocating screw 403 passes through the rotating hole and is rotatably connected to the rotating hole. The stabilizing seat 401 is used to limit the axial displacement of the reciprocating screw 403 and improve its rotational stability. A guide groove 501 is provided on the top inner wall of the U-shaped frame 102 along the length direction of the reciprocating screw 403. The top of the screw seat 201 is integrally formed with a guide seat 502. The guide seat 502 is embedded in the guide groove 501 and slides in cooperation with the guide groove 501. Through the cooperation between the guide seat 502 and the guide groove 501, the guide positioning of the reciprocating movement of the screw seat 201 is realized, and the screw seat 201 is prevented from rotating with the reciprocating screw 403.

[0027] In this embodiment, the detachable structure includes bolt grooves 301 on both sides of the output shaft of the vibratory motor 202, and bolt holes 302 on the inner walls of both sides of the mounting sleeve 203. The bolt holes 302 are threaded with internal hexagonal bolts 303. One end of the internal hexagonal bolts 303 is embedded in the bolt grooves 301 and fits tightly with the bolt grooves 301. The internal hexagonal bolts 303 are designed to prevent loosening, ensuring that the mounting sleeve 203 is reliably connected to the output shaft of the vibratory motor 202, while facilitating quick disassembly and assembly.

[0028] In this embodiment, a drive shaft 601 is rotatably mounted on the top of the base 101. The top of the drive shaft 601 extends to the inner wall of the top of the U-shaped frame 102 and is rotatably connected to the U-shaped frame 102. A driven bevel gear 603 is fixedly sleeved on the drive shaft 601. A drive bevel gear 602 is fixedly mounted on one end of the reciprocating screw 403 near the drive shaft 601. The drive bevel gear 602 meshes with the driven bevel gear 603 to transmit power between the reciprocating screw 403 and the drive shaft 601.

[0029] In this embodiment, a rotating gear 701 is fixedly sleeved on the transmission shaft 601, and an annular rack 702 is fixedly installed on the outer side wall of the rotating disk 103. The rotating gear 701 meshes with the rack 702 for transmission. Through the cooperation of the rotating gear 701 and the rack 702, the rotation of the transmission shaft 601 is converted into the rotational motion of the rotating disk 103.

[0030] In this embodiment, a rotating hole is provided at the bottom of the base 101, and a rotating shaft is rotatably installed in the rotating hole through a bearing. The top of the rotating shaft is fixedly connected to the bottom center of the rotating disk 103. The rotating shaft is used to achieve stable support and rotation of the rotating disk 103. Multiple evenly distributed shock-absorbing pads 105 are fixedly installed at the bottom of the base 101. The shock-absorbing pads 105 are made of rubber material and are used to absorb the vibration generated during the operation of the device, prevent the base 101 from shifting, and improve the overall stability of the device.

[0031] In this embodiment, a controller 8 is fixedly installed on one side of the U-shaped frame 102. The servo motor 402 and the vibrating motor 202 are both electrically connected to the controller 8. The controller 8 can realize the synchronous start, stop and operation parameter adjustment of the servo motor 402 and the vibrating motor 202, thereby improving the ease of operation.

[0032] In this invention, the well-mixed concrete is poured into the cylinder 104, and the cylinder 104 is placed steadily into the positioning sleeve 106, ensuring that the cylinder 104 and the positioning sleeve 106 fit together without looseness; the mounting sleeve 203 is fitted onto the output shaft of the vibrating motor 202, so that the bolt hole 302 and the bolt groove 301 are precisely aligned, and the internal hex bolt 303 is screwed in and tightened to ensure that the mounting sleeve 203 is reliably connected to the output shaft and to prevent it from falling off during vibration.

[0033] The servo motor 402's speed and the vibrating motor 202's vibration frequency are set by the controller 8, and the servo motor 402 and vibrating motor 202 are started. The servo motor 402 drives the reciprocating lead screw 403 to rotate. Since the lead screw seat 201 is limited by the guide seat 502 and the guide groove 501, the rotation of the reciprocating lead screw 403 is converted into the left and right reciprocating movement of the lead screw seat 201 along the guide groove 501. The lead screw seat 201 drives the vibrating motor 202 and the vibrating rod 204 to move back and forth synchronously. 04 The vibrator is inserted into the concrete and vibrates; at the same time, the reciprocating screw 403 drives the drive shaft 601 to rotate through the meshing of the drive bevel gear 602 and the driven bevel gear 603. The rotating gear 701 on the drive shaft 601 meshes with the rack 702 on the outside of the rotating disk 103, thereby driving the rotating disk 103 and the cylinder 104 to rotate slowly, realizing the compound vibration action of the vibrator 204 reciprocating left and right and the cylinder 104 rotating, ensuring that all areas inside the concrete can be fully vibrated.

[0034] According to the requirements for test block preparation, when the concrete surface is vibrated until there are no obvious air bubbles overflowing and the surface is covered with slurry, the servo motor 402 and the vibrating motor 202 are turned off by the controller 8; the internal hex bolt 303 is unscrewed in the opposite direction, the mounting sleeve 203 and the vibrating rod 204 are removed, and the vibrating rod 204 is cleaned and dried for later use; then the cylinder 104 inside the positioning sleeve 106 is taken out, and after the concrete has solidified, the concrete test block can be demolded to obtain the concrete test block, thus completing the entire vibration operation.

[0035] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
